I am trying to dual-boot Lubuntu and Windows XP on an old laptop, but I can't get it to install. This computer's optical drive doesn't work, so I have to boot from a flash drive using Plop Boot Manager. I can only occasionally get Lubuntu to load. It usually freezes at the initial boot menu after selecting one of the options.
When I can get it to load, the installer suddenly exits while copying files. No error messages are displayed, and the computer sits idle at that point (no CPU or disk activity). The cursor turns into the "busy" indicator and stays that way until I shut down. When I turn the computer back on, it displays some garbage graphics briefly and then loads Windows. What causes this? This is my first time installing Linux.
